Various issues related to oil palm production, such as biodiversity, drought, water scarcity, and water and soil resource exploitation, have become major challenges for environmental sustainability. The water footprint method indicates that the quantity of water used by plants to produce one biomass product could become a parameter to assess the environmental sustainability for a plantation. The objective of this study is to calculate the water footprint of oil palm on a temporal scale based on root water uptake with a specific climate condition under different crop age and soil type conditions, as a means to assess environmental sustainability. The research was conducted in Pundu village, Central Kalimantan, Indonesia. The methodology adopted in carrying out this study consisted of monitoring soil moisture, rainfall, and the water table, and estimating reference evapotranspiration (ETo), root water uptake, and the oil palm water footprint. Based on the study, it was shown that the oil palm water usage in the observation area varies with different crop ages and soil types from 3.07–3.73 mm/day, with the highest contribution of oil palm water usage was in the first root zone which correlates to the root density distribution. The total water footprint values obtained were between 0.56 and 1.14 m3/kg for various plant ages and soil types. This study also found that the source of green water from rainfall on the upper oil palm root zone delivers the highest contribution to oil palm root water uptake than the blue water from groundwater on the bottom layer root zone.

Various environmental challenges, related to oil palm commodity has became a major environmental challenge to oil palm production. The aim and objective of this study is to analyze the actual water footprint of oil palm based on root water uptake under varying crop age and soil type. The research was conducted in Pundu Village, Central Kalimantan. The methodology adopted in carrying out this study consists of various stages which includes observing soil moisture, rainfall, and water table, ETo, root water uptake and oil palm water footprint. The highest rate of water consumption was the 13 years oil palm on spodosol soil type with an average daily rate of 3.73 mm/day. The lowest evapotranspiration was represented by the 7th year oil palm on spodosol with an average rate of 3.07 mm/day. The total water footprint value obtained was between 0.56 – 1.14 m3/kg for a variety of plants with various age and soil types. It can be deduced that the water footprint value of oil palm vary for different crop age and soil types on temporal scale. The study also presented that the source of green water from the first root zone of oil palm deliver the highest contribution for oil palm root water uptake.

Farmers in Umbulrejo Village in Gunungkidul Regency, Yogyakarta are facing difficulties pumping water for their agriculture due to low electrical power availability. One alternative is to use solar-powered pumps, but this causes environmental problems and higher production costs. The Faculty of Agricultural Technology INSTIPER Yogyakarta is working with PT. Virama Karya to introduce the Clean Water and Irrigation Program for Umbulrejo Village Farmers, which includes planning, construction, operation, and monitoring of a ground water irrigation system with solar-powered pumps. The program's implementation is planned for 4 years and will include the construction of wells, water tanks, solar power plants, irrigation networks, and maintenance of the system. After 4 years, the village will own the system with guidance from the Stiper Agricultural Institute of Yogyakarta. Abstrak Petani di Desa Umbulrejo di Kabupaten Gunungkidul, Yogyakarta mengalami kesulitan memompa air untuk budidaya pertanian mereka karena ketersediaan tenaga listrik yang rendah. Salah satu alternatifnya adalah menggunakan pompa berbahan bakar solar, tetapi ini menimbulkan masalah lingkungan dan biaya produksi yang lebih tinggi. Fakultas Teknologi Pertanian INSTIPER Yogyakarta bekerja sama dengan Persero PT. Virama Karya untuk memperkenalkan program Penyediaan Air Bersih dan Air Irigasi untuk Petani Desa Umbulrejo yang mencakup perencanaan, pembangunan, operasional, dan monitoring sistem irigasi air tanah dengan pompa air tenaga surya. Pelaksanaan program direncanakan untuk 4 tahun dan akan mencakup pembangunan sumur, tandon air, pembangkit listrik tenaga surya, jaringan irigasi, dan pemeliharaan sistem. Desa akan menjadi pemilik sistem setelah 4 tahun dengan pendampingan dari Institut Pertanian Stiper Yogyakarta.

The objective of this research is to determine organic matter content in soil using image processing and artificial neural network. The images of soil were captured using digital camera and processed using image process algorithm. The images parameter data i.e. red, green, blue, hue, saturation, intensity, mean, entropy, energy, contrast, and

Brown sugar is one of the palm derivative products that have high economic value and has very good prospects for development. Commerce is a trading activity that combines the flow of goods and services from the level of production to consumption. This study aims to determine the share margin received by each channel of the brown sugar commerce at Kulon Progo Regency. This research, which was conducted in May-July 2020, used a descriptive method. The method of determining the research location used the purposive sampling method. Determination of the number of informants is determined by the snowball method with a total of 60 informants. Methods of data analysis using cost analysis tools and marketing margins. The results showed that the marketing margin obtained at the farm level was Rp1.706/kg while the collectors were Rp4.375/kg. Product variations being developed are printed coconut sugar, wet neutral brown sugar, dry neutral brown sugar, and flavor variants.
